Feature → Business Impact → Application: Three main NO contacts in a 3-pole block design simplify wiring and improve reliability for three‑phase motor control, reducing panel complexity and installation time in automated lines. This translates to lower commissioning costs and faster deployment in packaging, pumping, and conveying systems. Application example includes conveyor drives in material handling where space is at a premium and consistent switching is essential. Feature → Business Impact → Application: Rated Operational Current AC-3 up to 53 A at 690 V and up to 50 A at 415 V enables efficient motor starting and running with compact devices, improving energy efficiency and reducing cabinet size in bottling and process lines. Feature → Business Impact → Application: AC operated control circuit at 50/60 Hz with a responsive operate time of 7 to 14 ms ensures precise motor start/stop sequences in automation panels and pump stations. Feature → Business Impact → Application: Optional add-on auxiliary contact blocks allow side mounting and scalable control, supporting future expansion without replacing the base unit in OEM machines. Feature → Business Impact → Application: Low power loss per pole — 5 W for AC-1 and 1.3 W for AC-3 — lowers standby heat and cooling requirements, cutting running costs in continuous duty environments like extruders and mixers. Feature → Business Impact → Application: IP20 coil terminals and IP10 main terminals, with screw terminals and specified tightening torques, provide robust wiring integrity and serviceability in harsh factory environments such as metal fabrication and food & beverage lines. Feature → Business Impact → Application: Compact dimensions (70 mm W x 110 mm D x 108 mm H) and a weight of 1.01 kg simplify mounting in control cabinets and space-constrained panels for automation upgrades.

FAQs
Install the 3-pole block contactor by aligning it with standard 35 mm DIN rail or panel mounting as per IEC 60947-4-1 guidelines. Use screw terminals for main and control circuits, tighten to 4 N·m on the main circuit and 1 N·m on the control circuit, and connect 230–240 V or 240–260 V control voltage per frequency. Optional add-on auxiliary blocks can be mounted on the side for expanded signaling without changing the base device.
For AC-3 operation, the device provides defined Ie values that depend on voltage: up to approximately 50–53 A at 415–440/380 V and 35–45 A at higher 500–690 V ranges, with Pe values around 22–30 kW depending on voltage. Ui is 690 V, and the device supports up to 50 Hz at 415–690 V, ensuring reliable motor starting for standard industrial motors.
Yes. The 1SBL351074R8800 is a 3-pole contactor designed for 3-phase motors up to 690 V and up to 53 A AC-3, which covers many conveyor drive motors. Its compact footprint, fast operate times, and compatibility with auxiliary contact blocks make it a good fit for tight panel spaces and scalable control in packaging automation.
The unit carries CE and UL certifications, and it is supported by CCC and CQC declarations. REACH and RoHS compliance are declared, with WEEE categorization for B2B use. These certifications facilitate global procurement and reduce compliance risk for international panel build projects.
The device delivers low coil power loss (5 W per pole at AC-1 and 1.3 W per pole at AC-3), reducing heat and cooling needs in control panels. Its robust IP20 coil terminals and IP10 main terminals, plus screw-terminal design and defined tightening torques, simplify maintenance and reworks. The compact, lightweight design also supports smaller, more cost-efficient control cabinets, improving total cost of ownership in automation projects.
